A flat car of mass m0 starts moving to the right due to a constant horizontal force ‘F’ at t = 0. Sand spills on the flat car from stationary hopper, the velocity of loading is constant and is equal to u kg s−1. Then
( A )
initial acceleration is equal to F/ m0 ( B )
acceleration at time t is F/ m0+ ut ( C )
initial acceleration is less than F/ mo ( D )
initial acceleration is greater than F/ m0
